Description

Technical Field

[0001] This application belongs to the field of refrigeration technology, and in particular relates to a storage device. Background Technology

[0002] To achieve uniform and shadowless lighting, refrigerators currently use surface light sources.

Compared with the related technology that requires the arrangement of light strips in multiple directions, this greatly simplifies the structure and space occupied by the lighting components, reduces manufacturing costs, and improves the storage capacity of the compartment. On the other hand, since the elongated hole will destroy the reflection and refraction of light, by making the extension direction of the elongated hole parallel to the arrangement direction of the light source and the light guide plate, the obstruction of light can be minimized. Combined with the reinforcement area being at least partially positioned opposite the side of the elongated hole away from the light source, and increasing the area ratio of the light guide portion located in the reinforcement area, the brightness of the side of the elongated hole away from the light source is compensated, thereby maintaining the uniformity of light throughout the compartment.

The storage device further includes: An air duct structure is provided inside the box and has a ventilation channel, wherein the air supply hole and the ventilation channel are connected.

[0008] According to one embodiment of this application, a plurality of air supply holes are provided, and the plurality of air supply holes are distributed at intervals along the vertical direction.

[0009] According to one embodiment of this application, multiple reinforcement zones are provided, and the reinforcement zones correspond to the air supply holes.

[0010] According to one embodiment of this application, the elongated hole includes a mounting hole extending in a vertical direction, and the light source is disposed on the upper or lower side of the light guide plate. The storage device further includes: Shelves are located within the room; A connector is provided on the housing, and the front part of the connector is connected to the rear part of the shelf through the mounting hole.

[0011] According to one embodiment of this application, the reinforcing region is an isosceles trapezoid; and / or The light guide portion protrudes from the side of the light guide plate facing the opening, and the projection of the light guide portion on the light guide plate is circular.

[0012] According to one embodiment of this application, the light-guiding area of ​​at least a portion of the light-guiding portion located in the enhanced region is greater than the light-guiding area of ​​at least a portion of the light-guiding portion located in the remaining region; and / or The density of the light guide located in the enhanced area is greater than the density of the light guide located in the other areas.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0019] The following is for reference. Figures 1-6The present application describes a storage device including a housing 100 and a lighting assembly 200.

[0020] It should be noted that storage equipment can be understood as refrigeration and storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage equipment has diverse structural forms and a wide range of applications. As a specific example, this application embodiment uses a vertical refrigerator as an illustration.

[0021] The housing 100 forms a compartment 101 with an opening. It should be noted that the size and shape of the compartment 101 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0022] A lighting assembly 200 is disposed within the chamber 101. The lighting assembly 200 includes a light source 210 and a light guide plate 220. The light source 210 is disposed on one side of the light guide plate 220. The light guide plate 220 has an elongated hole 221, the extension direction of which is parallel to the arrangement direction of the light source 210 and the light guide plate 220. A plurality of light guide portions 223 are disposed on the side of the light guide plate 220 facing the opening. The light guide plate 220 also has a reinforcement area 222, which is located on the side of the elongated hole 221 away from the light source 210. Along the direction away from the light source 210, the projection of the reinforcement area 222 and the projection of the elongated hole 221 at least partially overlap, and the area ratio occupied by the light guide portion 223 located in the reinforcement area 222 is greater than the area ratio occupied by the light guide portion 223 located in the other areas.

[0023] Understandably, on the one hand, since the light sources 210 are all located on one side of the light guide plate 220, compared to the need to arrange light strips in multiple directions in related technologies, the structure and space occupied by the lighting assembly 200 can be greatly simplified, manufacturing costs can be reduced, and the storage capacity of the compartment 101 can be improved. On the other hand, since the elongated hole 221 will disrupt the reflection and refraction of light, by making the extension direction of the elongated hole 221 parallel to the arrangement direction of the light source 210 and the light guide plate 220, the obstruction of light can be minimized. Combined with the reinforcement area 222 being at least partially positioned opposite the side of the elongated hole 221 away from the light source 210, and increasing the area ratio of the light guide portion 223 located in the reinforcement area 222, the brightness of the side of the elongated hole 221 away from the light source 210 is compensated, thereby maintaining the uniformity of light throughout the compartment 101.

[0024] The storage device provided according to the embodiments of this application ensures uniform light in the compartment 101 while reducing the manufacturing cost and structural complexity of the storage device and optimizing the space utilization of the compartment 101.

[0025] In some embodiments, the light guiding area of ​​at least a portion of the light guide portion 223 located in the reinforcement region 222 is greater than the light guiding area of ​​at least a portion of the light guide portion 223 located in the remaining regions.

[0026] It is understood that the light guiding area refers to the effective area of ​​a single light guiding part 223 in contact with and scattering light. By increasing the size of at least a portion of the individual light guiding parts 223 in the reinforcement zone 222, the light guiding capability of the individual light guiding parts 223 is improved, and light can be guided more effectively, allowing the light to be fully diffused and propagated in the reinforcement zone 222, further improving the uniformity of illumination, reducing the attenuation of light in the direction away from the light source 210, and enhancing the lighting effect.

[0027] In some embodiments, such as Figure 2 and Figure 5 As shown, the density of light guides 223 located in the reinforcement zone 222 is greater than the density of light guides 223 located in the other regions.

[0028] It is understandable that density refers to the number of light guides 223 per unit area. By adjusting the distance between adjacent light guides 223, the arrangement of light guides 223 in the enhancement area 222 becomes denser, thereby guiding light more effectively, allowing light to be fully diffused and propagated in the enhancement area 222, further improving the uniformity of illumination, reducing the attenuation of light in the direction away from the light source 210, and enhancing the lighting effect.

[0029] In some embodiments, such as Figure 2 and Figure 5 As shown, the length of the side of the reinforcing region 222 closest to the elongated hole 221 is less than the length of the side of the reinforcing region 222 furthest from the elongated hole 221.

[0030] Understandably, the reinforcement area 222 is non-rectangular, meaning that the narrow side of the reinforcement area 222 is close to the elongated aperture 221, and the wide side of the reinforcement area 222 is far away from the elongated aperture 221. This means that by using the monotonically increasing width of the reinforcement area 222 along the direction away from the light source 210, it can not only match the physical phenomenon that the light intensity naturally decreases with the increase of the propagation distance and improve the uniformity of the light, but also reduce the possibility of sudden brightness changes, and keep the brightness of the reinforcement area 222 consistent with the brightness of the surrounding area, thereby obtaining better visual uniformity.

[0031] In some embodiments, such as Figure 2 and Figure 5 As shown, the reinforcing zone 222 is symmetrically arranged relative to the elongated hole 221.

[0032] It is understandable that the reinforcement zone 222 is symmetrically arranged along the long axis centerline of the elongated hole 221, which can ensure that the behavior of light diffraction and conduction from both sides of the elongated hole 221 is symmetrical, balance the light field distribution, and simplify the structural design and processing technology of the light guide plate 220.

[0033] In some embodiments, such as Figure 2 and Figure 5 As shown, the reinforced area 222 is an isosceles trapezoid.

[0034] Understandably, using an isosceles trapezoidal reinforcement zone 222 not only ensures symmetrical and balanced optical compensation on both sides, improving the uniformity of illumination, but also utilizes the hypotenuse of the trapezoid to provide a linear and continuous gradient boundary, achieving a natural transition of brightness from the reinforcement zone 222 to the normal area.

[0035] In some embodiments, such as Figure 2 and Figure 5 As shown, along the extension direction of the elongated hole 221, one side of the reinforcing region 222 coincides with the edge portion of the elongated hole 221.

[0036] Understandably, one side of the reinforcement area 222 at least partially overlaps with the side of the elongated aperture 221 away from the light source 210, ensuring that optical compensation starts from the edge of the elongated aperture 221 and maximizes the efficiency of optical compensation.

[0037] In some embodiments, the light guide portion 223 protrudes from the side of the light guide plate 220 facing the opening, and the projection of the light guide portion 223 on the light guide plate 220 is circular.

[0038] It is understandable that the circular and raised light guide 223 has consistent and uniform scattering characteristics of light in all directions, which helps to achieve uniformity of illumination, reduces stress concentration, and improves the reliability of the light guide plate 220.

[0039] For example, the light guide portion 223 protrudes from the front surface of the light guide plate 220.

[0040] In some embodiments, the light guiding area of ​​the light guide portion 223 located in the remaining area increases monotonically along the direction away from the light source 210.

[0041] It is understandable that in the area outside the enhancement zone 222, the size of the light guide point near the light source 210 is smaller than the size of the light guide point far away from the light source 210, thereby compensating for the decrease in brightness caused by the increase in distance and improving the uniformity of illumination.

[0042] In some embodiments, the density of the light guide portion 223 in the remaining area increases monotonically along the direction away from the light source 210.

[0043] It is understandable that in the area outside the enhancement zone 222, the number of light guide points near the light source 210 is less than the number of light guide points far from the light source 210, thereby compensating for the decrease in brightness caused by the increase in distance and improving the uniformity of illumination.

[0044] In some embodiments, such as Figure 3 As shown, the light source 210 includes a substrate 211 and a plurality of LED beads 212. The plurality of LED beads 212 are spaced apart on the side of the substrate 211 facing the light guide plate 220, and the arrangement direction of the LED beads 212 intersects the extension direction of the elongated hole 221. It should be noted that the number and specific distribution of the LED beads 212 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0045] It is understandable that the LED beads 212 emit light towards the side of the light guide plate 220, and the arrangement direction of the multiple LED beads 212 intersects with the extension direction of the elongated hole 221, so that the light generated by the multiple LED beads 212 overlaps and mixes with each other in the width direction of the light guide plate 220, making the light source 210 as compact as possible, while also making the light that does not enter the light guide plate 220 as uniform as possible.

[0046] In some embodiments, such as Figure 6 As shown, the lighting assembly 200 also includes a reflector 230 and a diffuser 240. The reflector 230 is disposed on the side of the light guide plate 220 away from the opening, and the diffuser 240 is disposed on the side of the light guide plate 220 close to the opening.

[0047] It is understandable that the reflector 230 reflects light multiple times, and the diffuser 240 scatters and refracts light multiple times, thereby improving light utilization and enhancing uniformity.

[0048] For example, the opening of the chamber 101 faces forward, and the diffuser plate 240, the light guide plate 220 and the reflector 230 are arranged sequentially from front to back, and the light guide portion 223 is disposed on the front surface of the light guide plate 220.

[0049] In some embodiments, such as Figures 1 to 3 As shown, the elongated hole 221 includes an air supply hole that extends in the left-right direction. A light source 210 is provided on the left or right side of the light guide plate 220. The storage device also includes an air duct structure, which is set inside the housing 100 and has a ventilation channel. The air supply hole and the ventilation channel are connected. It should be noted that the shape and size of the air duct structure can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0050] Understandably, the elongated opening 221 includes an air supply hole connected to the ventilation channel, integrating lighting and ventilation functions. This not only saves space but also improves the overall performance of the storage equipment. Furthermore, by utilizing the structural characteristics of the air supply hole, the design of the light guide plate 220 is further optimized, resulting in more uniform lighting, simplifying the structural complexity within the compartment 101, reducing manufacturing costs, and maximizing the air supply area.

[0051] For example, such as Figure 3 As shown, the air outlet extends in the left and right direction, and the light source 210 is located on the left side of the light guide plate 220.

[0052] In some embodiments, such as Figures 1 to 3 As shown, multiple air supply holes are provided, and these holes are spaced apart along the vertical direction. It should be noted that the number and distribution of the air supply holes can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0053] Understandably, the multiple air vents are spaced vertically to distribute air more evenly into the room 101, further improving air circulation.

[0054] In some embodiments, such as Figures 1 to 3 As shown, multiple reinforcement zones 222 are provided, and each reinforcement zone 222 corresponds to an air supply vent.

[0055] Understandably, by strengthening the corresponding settings of zone 222 and the air supply holes, it can be ensured that the side of each air supply hole away from the light source 210 can receive the most effective compensation, further optimizing the propagation and distribution of light, reducing manufacturing costs while improving the uniformity of lighting.

[0056] In some other embodiments, such as Figures 4 to 6 As shown, the elongated hole 221 includes a mounting hole that extends in the vertical direction. A light source 210 is provided on the upper or lower side of the light guide plate 220. The storage device also includes a shelf 310 and a connector 320. The shelf 310 is located inside the compartment 101. The connector 320 is provided on the housing 100, and the front part of the connector 320 is connected to the rear part of the shelf 310 through the mounting hole.

[0057] Understandably, compared to similar technologies where shelves 310 are typically mounted on the left and right side walls of compartment 101 via brackets or slide rails, the front end of connector 320 extends directly into compartment 101 through mounting holes to support the shelf 310. This effectively increases the width of compartment 101, reducing hard-to-clean areas and improving storage capacity. By utilizing mounting holes, the lighting component 200 and shelf 310 are integrated, saving space while improving the structural stability and aesthetics of the storage equipment.

[0058] For example, such as Figures 4 to 6 As shown, the mounting holes extend in the vertical direction, and the light source 210 is located on the upper side of the light guide plate 220.

[0059] In some embodiments, mounting holes are formed in the middle of the light guide plate 220 to provide more balanced and stable support for the shelf 310, improve structural stability, load-bearing capacity and space utilization, and increase the storage capacity of the compartment 101.

[0060] In some embodiments, such as Figure 4 As shown, multiple shelves 310 and connectors 320 are provided and correspond one-to-one. Multiple shelves 310 are distributed at intervals in the vertical direction to make full use of the vertical space of the compartment 101 and increase the storage capacity.
